Jonathan is a very good student and competent computer
technician. He’s generally antisocial, happy to just keep to
himself and get his work done quietly without bothering anyone.
Because of this, people tend to forget he’s there, or assume
he’s a jerk who can’t make friends and won’t smile. In reality,
however, he’s actually very thoughtful and courteous.

Jon tends to approach life as if it were a computer problem of a
complex equation. He carefully plans each step and doesn’t like
surprises. People find this disconcerting, and so he hasn’t
managed to make any long-term friends except for Jessica Waymire,
who he’s known since they were both children back in the UK.
